Sponge Rubber Revealed Two Years After Penetrating Injury: A Case Report.

The present report illustrates a very rare case report of a foreign body granuloma of the foot associated with a 2-year period of a retained spongeous rubber foreign body after a penetrating injury. Because it appeared almost 2 years after the injury, the history of trauma was minimized, the foreign body had migrated from the plantar to the dorsal side of the foot, and the radiographic appearance resembled a malignant process, it was difficult to rule out the possibility of a malignant tumor. This case shows the weakness of magnetic resonance imaging in detecting spongeous rubber in the body. Also, a bone osteoblastic reaction to the foreign body has very rarely been noted. To the best of our knowledge, just 5 cases have been previously reported. Provided suspicion exists of previous trauma with an embedded foreign body, the differential diagnosis of a bone neoplasm should consider the possibility of a foreign body reaction. Biopsy proved to be the best diagnostic tool.

Navicular index for differentiation of flatfoot from normal foot.

PURPOSE: The height of navicular bone from the floor is in proportion with the height of longitudinal arch of the foot. The study was conducted to evaluate correlation of navicular bone height with most often used angles, heel valgus and a foot print in order to simplify the procedure for the diagnosis of flatfoot. METHODS: A total of 218 operated children (436 feet) because of flexible flatfoot were evaluated clinically and radiologically. Meary angle, lateral talonavicular angle, talocalcaneal angle, calcaneal pitch, heel valgus and arch index (Staheli) were evaluated pre-operatively and postoperatively. In 121 (242 feet) chosen children (age eight to 15) with all clinical values and pre-operative angles corresponding flatfoot, all postoperatively measured values were within the normal range. We got the navicular index by dividing length of longitudinal arch with navicular height. Values of navicular index were then compared with pre-operatively and postoperatively measured values. Pearson correlation and ROC test were used for statistical analysis. RESULTS: Values of the navicular index for flatfeet were in the interval from 4.75 to 31.2 (median 8.98), and for normal-arched feet 3.58-22.6 (median 5.48). Pearson correlation of arch index and measured parameters were significant in majority, and degree according to Colton was good. Area under the ROC curve was 0.861 (p = 0.0001). The cut-off value with 86 % sensitivity and 75 % specificity was 6.7407. CONCLUSION: Navicular index can be used reliably, without measures of the other parameters, to differentiate flatfoot from normal-arched foot. Therefore, the navicular index has an ability to distinguish between the flatfoot and normal-arched foot.

Influence of arthroscopic lateral release on functional recovery in adolescents with recurrent patellar dislocation.

INTRODUCTION: The aim of this study is to prove the influence of the arthroscopic lateral release on functional recovery in adolescents with recurrent lateral dislocation of patella. MATERIALS AND METHODS: From 2006 to 2009, arthroscopic release of the lateral retinaculum was done on 27 adolescent patients (24 women, 3 men) and 33 knees (in 6 patients on both knees). All of them were active in different sports. The severity of patellar subluxation and dislocation was analysed on X-ray; the Q angle, congruence angle, sulcus angle, patellofemoral angle and height ratio were measured. Functional scores (Lysholm, Kujala, Tegner) were measured preoperatively and postoperatively. The average duration of clinical and X-ray follow-up was 4.5 years (range 3-6 years). RESULTS: The mean age of the patients was 14.56 years (range 11-18 years). There was an average of 4.16 dislocations (range 2-28 dislocations) before surgery. The mean Lysholm score improved from 64 to 95 (p = 0.0002), and the mean Kujala score improved from 66 to 94 (p < 0.0001). Congruence angle and lateral patellofemoral angle improved but without any significant differences. CONCLUSION: Arthroscopic lateral release successfully treats recurrent patellar dislocations in adolescents, influences functional recovery and improves knee function.

Tibial stress fracture simulate osteomyelitic foci in the course of chronic recurrent multifocal osteomyelitis.

Chronic recurrent multifocal osteomyelitis (CRMO) is an extremely rare and most severe form of chronic nonbacterial osteomyelitis of unknown etiology. Here we present the first case of a six-year-old girl in which was observed that the stress fracture mimic osteomyelitic foci in the course of CRMO.

Calcaneo-stop procedure for paediatric flexible flatfoot.

BACKGROUND: Flexible flatfoot is a frequent deformity found in children. The aim of this study is to evaluate the pedographic outcome of the percutaneous arthroereisis with the use of a screw through the sinus tarsi into the talus. MATERIALS AND METHODS: 43 calcaneo-stop procedures of 25 patients (18 bilateral, seven unilateral) were evaluated. Mean age at surgery was 10 years (7-14, SD 2.2) (SD: standard deviation), mean follow-up time was 9.7 months (3-19, SD 5.5). Patient satisfaction rate was recorded, the Meary's talus-first metatarsal angle was measured with lateral radiograms, and a dynamic pedographic assessment was also performed. RESULTS: Patient satisfaction rate was excellent for 33 feet of 19 children, good for eight feet of five children, and poor for either feet of one child. We did not observe any complications during or following the surgery.The mean rest heel valgus decreased from 13.4° (10°-17°, SD 1.5) to 2.8° (0°-6°, SD 1.7) post op. The Meary's angle improved from 160.2° (148°-177°, SD 6.8) to 175.9° (167°-179°, SD 3.5). By pedographic analysis, the area and the pressure-time integral (load amount, PTI) values increased on the lateral regions of the sole (except for the lesser toes) and decreased on the medial areas (except for the hallux). The relative contact time in the lateral midfoot increased from 63.8% (39.6-78.4%, SD 10.6) to 75.1% (50-86.1%, SD 9.4), and that in the lateral forefoot region from 81.2% (60.4-89.2%, SD 6.6) to 86.8% (78.1-97.1%, SD 4.8). CONCLUSION: The calcaneo-stop procedure is a simple and reliable method for the correction of severe flexible paediatric flatfoot. Our prospective, short-term results following the anterograde screw implantation into the talus correlate well with the results of similar or different arthroereisis methods. Further investigations are required to evaluate the long-term outcome of the screw calcaneo-stop method, including the conditions following implant removal.

Results of treatment of displaced supracondylar humeral fractures in children by K-wiring.

The supracondylar fracture of the humerus in children remains the most challenging injury for the orthopedic surgeon. It is important to consider the options of treatment very carefully and tailor the treatment according to the characteristics of each fracture. In this study we observed outcomes of surgical procedures using the Kirschner-wire for the dislocated (displaced) supracondylar fractures in 135 children (mean age 6.7 years). In 96 patients closed reposition (reduction) and fixation with crossed K-wire was done. A total of 41 children were operated by the means of open reposition and crossed K-wire fixation. Another 41 underwent similar (1-mm) K-wire application. In classifying the fractures Gartland classification of the supracondilar fractures of the humerus was used. Postoperatively, cubitus varus was found in seven, and cubitus valgus in three children (5% and 2% respectively). Stiffness of the elbow was recorded in 18 patients, while the paresis of the ulnar nerve was recorded in three cases (13 and 2% respectively). In conclusion, we can suggest crossed fixation while applying the K-wire throughout two cortexes, since such technique ensures the most superior fixation and stable osteosynthesis.

Treatment of peritrochanteric fractures by the use of gamma nail.

The Gamma nail was designed to treat unstable intertrochanteric and subtrochanteric fractures. In this study we analysed a total of 60 patients (44 men and 16 women), who were surgically treated for the peritrochanteric fracture in period 2006-2007 at the University Hospital Mostar. After the surgical treatment good bone healing was achieved in 50 patients (83.3%). A total of five patients had delayed healing or protrusion of the cervical screw, and in two patients nails were not appropriately distally locked. During the follow-up period a total of 7 patients died. The average operation time was 40 minutes, and the average blood loss was 400 mL, which is a comparable result with the previously published studies. In conclusion, although most of the peritrochanteric fractures treated at the University Hospital Mostar were fixated by gamma nail, the final decision regarding the operational technique should be left to surgeon's judgment, since the efficacy of the treatment plan is highly dependent on experience of the operational team and surgeon's operational technique.

Bilateral congenital dislocation of the knee with ipsilateral developmental dysplasia of the hip--report of three patients.

Congenital dislocation of the knee (CDK) is a very rare condition. Here we report our strategy and results in treatment of three children with CDK. All three patients were treated with conservative method, and only one had underwent a surgical procedure on one knee. Of the remaining, we recorded a good outcome with conservative treatment in three knees, while two had poorer outcome as a result of musculoskeletal anomalies. We also present here a unique case of a child born without cruciate ligaments and patellas on both sides. We performed the operative procedure by Z-plasty of the extensor apparatus on one left knee according to Niebauer and King on one child. The clinical result of this procedure was very good. Five years after the operation we decided to perform an MRI examination to assess the postoperative status of the operated knee, especially the position and the shape of left patella. We found the asymmetry and high position of the operated patella resulting in patella alta. Compared to the initial clinical presentation, we consider all patients to have good clinical presentation nowdays.

Giant pseudocyst of the rectus femoris muscle--repetitive strain injury in recreational soccer player.

We report a case of a traumatic pseudocyst, in a recreational soccer player, after rupture of rectus femoris muscle. 37-year-old male, with history of repetitive painful accidents, was examined because of a double fist-sized mass in the anterior thigh. Ultrasound examination revealed a cystic mass in the rectus femoris muscle. Surgical removal of the mass and proximal remnant of muscle was done. Primary healing and functional recovery was achieved. Histological analysis revealed pseudocyst filled with degenerating clot and surrounded with thick fibrous capsule. The repetitive strain muscle injury, with prolonged period of healing, can occur like pseudocyst.

Comparative outcome analyses of differently surgical approaches to lumbar disc herniation.

Lumbar disc herniations (LDH) occur in the lower back, most often between the fourth and fifth lumbar vertebral bodies or between the fifth and the sacrum. It is evident lack of studies dealing with comparative analysis of the surgical outcomes of the spine operation techniques. In this paper we analyzed and compared outcomes of the LDH standard techniques (laminectomy and hemilaminectomy), and contemporary operation techniques (interlaminectomy, and micro-discectomy). Adult patients (18-75 years of age) surgically treated on the Neurosurgery Department of the University Clinical Hospital Mostar - Bosnia and Herzegovina between January 1998 and December 2007 were sampled as subjects. We analyzed and compared, number of the LDH surgically treated patients; age, patient's satisfaction with postoperative status, postoperative recurrence of the LDH; incidence of the postoperative complications, and duration of hospitalization. In conclusion, modern operating methods have to be considered as superior over traditional operating types mostly because of smaller violations of forms and integrity of lumbar spine.

Keller's arthroplasty with proximal metatarsal opening wedge osteotomy in treating severe Hallux valgus deformity--surgical techniques and case report.

The paper presents an operative technique proposed for treating severe Hallux Valgus deformity with arthrosis of the first metatarsal joint in elderly people. The procedure consists of the Keller's arthroplasty in combination with basal osteotomy of the first metatarsal bone, whereby the head of the metatarsal is displaced laterally and plantarward. The osteotomy is fixed with a reconstructive plate. The results show a significant improvement in the hallux valgus angle, the first metatarsal angle, as well as in the plantar pressure distribution.

Bilateral fibular stress fracture in young female basketball player.

This report is a unique case of three stress fractures in a 14-year-old active female basketball player and we emphasize the importance of triple-phase bone scanning in differential diagnosis of the stress fracture. According to radiographic examination and laboratory tests, which were normal, the stress fracture of the right fibula was strongly suspected while making the diagnosis. Despite the treatment applied, recurrence, and deterioration of the symptoms were presented. Repeated laboratory test results were again normal, but the presence of an abundant periosteal reaction on the plain radiographs was confusing, so osteomyelitis or Ewing sarcoma of the fibula was suspected. We decided to perform a three-phase bone scanning; its findings were critical for the judgment and we diagnosed three stress fractures involving both fibulae. Final confirmation of the diagnosis of the bilateral fibular stress fractures in our case, however, was done by computed tomography examination.

Minimally invasive calcaneo-stop method for idiopathic, flexible pes planovalgus in children.

BACKGROUND: The aim of this study was to correct heel valgus in children and to lift the longitudinal arch of the foot using a temporary cancellous screw placed percutaneously across the talocalcaneal articulation. METHODS: From April, 1997, to June, 2003, 94 procedures were done on 48 children between the ages of 8 and 14 years. The Meary angle to determine the degree of collapse of the medial longitudinal arch was 170 degrees or less, and the weightbearing hindfoot was in valgus. Presumably, the screw achieves correction by stimulating the proprioceptive foot receptors allowing active inversion of the foot. RESULTS: At 5 years followup, no serious complications occurred. The correction of the Meary angle on average was 17.10 +/- 5.51 degrees. In every foot, heel valgus and the longitudinal arch of the foot were improved radiographically and clinically without the loss of function. We removed the screws in all patients. In 91 feet, the arch of the foot and heel valgus remained in the corrected position. CONCLUSIONS: The 'calcaneo-stop' method is a simple, effective, minimally invasive technique for the treatment of idiopathic, flexible pes planus in carefully selected pediatric patients.

Synovial chondromatosis of the pisotriquetral joint with secondary osteoarthritis: case report.

There are only a few reported cases of synovial chondromatosis affecting pisotriquetral joint (PT). Osteoarthritis of the PT is also rare and can be as disabling as osteoarthritis of any other joint. We report this to be the unique case of synovial chondromatosis of the PT joint with secondary osteoarthritis.
